I have a HP Mini laptop. If I stay near an external electrical power source, is it right to power the laptop from this source if the battery is not empty?

Generally yes, I'd use the power source instead of the battery when available.
But keep in mind...
A battery should not be left charged in a dormant state for a very long time. After it is fully charged you should use it at least once every few weeks at a bare minimum to extend battery life. If you are using an older lithium-ion battery, avoid letting its charge drop to 0. Lithium-ion batteries typically have what is called a discharge/charge cycle of 300-500.

You shuould.Avoid allowing the battery to drop below 5% of capacity because most new versions of the Windows OS will automatically put your laptop computer in a forced “hibernation” mode which may cause the loss of some projects you are working on.Only remove or install a laptop battery when your computer is turned off, this will avoid any current surge that could harm your new battery.
